Predictive value of red blood cell distribution width and hematocrit for short-term outcomes and prognosis in colorectal cancer patients undergoing radical surgery

BACKGROUND Previous studies have reported that low hematocrit levels indicate poor survival in patients with ovarian cancer and cervical cancer,the prognostic value of hematocrit for colorectal cancer(CRC)patients has not been determined.The prognostic value of red blood cell distribution width(RDW)for CRC patients was controversial.AIM To investigate the impact of RDW and hematocrit on the short-term outcomes and long-term prognosis of CRC patients who underwent radical surgery.METHODS Patients who were diagnosed with CRC and underwent radical CRC resection between January 2011 and January 2020 at a single clinical center were included.The short-term outcomes,overall survival(OS)and disease-free survival(DFS)were compared among the different groups.Cox analysis was also conducted to identify independent risk factors for OS and DFS.RESULTS There were 4258 CRC patients who underwent radical surgery included in our study.A total of 1573 patients were in the lower RDW group and 2685 patients were in the higher RDW group.There were 2166 and 2092 patients in the higher hematocrit group and lower hematocrit group,respectively.Patients in the higher RDW group had more intraoperative blood loss(P<0.01)and more overall complications(P<0.01)than did those in the lower RDW group.Similarly,patients in the lower hematocrit group had more intraoperative blood loss(P=0.012),longer hospital stay(P=0.016)and overall complications(P<0.01)than did those in the higher hematocrit group.The higher RDW group had a worse OS and DFS than did the lower RDW group for tumor node metastasis(TNM)stage I(OS,P<0.05;DFS,P=0.001)and stage II(OS,P=0.004;DFS,P=0.01)than the lower RDW group;the lower hematocrit group had worse OS and DFS for TNM stage II(OS,P<0.05;DFS,P=0.001)and stage III(OS,P=0.001;DFS,P=0.001)than did the higher hematocrit group.Preoperative hematocrit was an independent risk factor for OS[P=0.017,hazard ratio(HR)=1.256,95%confidence interval(CI):1.041-1.515]and DFS(P=0.035,HR=1.194,95%CI:1.013-1.408).CONCLUSION A higher preoperative RDW and lower hematocrit were associated with more postoperative complications.However,only hematocrit was an independent risk factor for OS and DFS in CRC patients who underwent radical surgery,while RDW was not.

Red cell distribution width/platelet ratio estimates the 3-year risk of decompensation in Metabolic Dysfunction-Associated Steatotic Liver Disease-induced cirrhosis

BACKGROUND For compensated advanced chronic liver disease(cACLD)patients,the first decompensation represents a dramatically worsening prognostic event.Based on the first decompensation event(DE),the transition to decompensated advanced chronic liver disease(dACLD)can occur through two modalities referred to as acute decompensation(AD)and non-AD(NAD),respectively.Clinically Significant Portal Hypertension(CSPH)is considered the strongest predictor of decompensation in these patients.However,due to its invasiveness and costs,CSPH is almost never evaluated in clinical practice.Therefore,recognizing noninvasively predicting tools still have more appeal across healthcare systems.The red cell distribution width to platelet ratio(RPR)has been reported to be an indicator of hepatic fibrosis in Metabolic Dysfunction-Associated Steatotic Liver Disease(MASLD).However,its predictive role for the decompensation has never been explored.AIM In this observational study,we investigated the clinical usage of RPR in predicting DEs in MASLD-related cACLD patients.METHODS Fourty controls and 150 MASLD-cACLD patients were consecutively enrolled and followed up(FUP)semiannually for 3 years.At baseline,biochemical,clinical,and Liver Stiffness Measurement(LSM),Child-Pugh(CP),Model for End-Stage Liver Disease(MELD),aspartate aminotransferase/platelet count ratio index(APRI),Fibrosis-4(FIB-4),Albumin-Bilirubin(ALBI),ALBI-FIB-4,and RPR were collected.During FUP,DEs(timing and modaities)were recorded.CSPH was assessed at the baseline and on DE occurrence according to the available Clinical Practice Guidelines.RESULTS Of 150 MASLD-related cACLD patients,43(28.6%)progressed to dACLD at a median time of 28.9 months(29 NAD and 14 AD).Baseline RPR values were significantly higher in cACLD in comparison to controls,as well as MELD,CP,APRI,FIB-4,ALBI,ALBI-FIB-4,and LSM in dACLD-progressing compared to cACLD individuals[all P<0.0001,except for FIB-4(P:0.007)and ALBI(P:0.011)].Receiving operator curve analysis revealed RPR>0.472 and>0.894 as the best cut-offs in the prediction respectively of 3-year first DE,as well as its superiority compared to the other non-invasive tools examined.RPR(P:0.02)and the presence of baseline-CSPH(P:0.04)were significantly and independently associated with the DE.Patients presenting baseline-CSPH and RPR>0.472 showed higher risk of decompensation(P:0.0023).CONCLUSION Altogether these findings suggest the RPR as a valid and potentially applicable non-invasive tool in the prediction of timing and modalities of decompensation in MASLD-related cACLD patients.

The Prognostic Value of Red Cell Distribution Width in Critically Ill Cerebral Infarction Patients:A Retrospective Cohort Study

Objective:Red blood cell distribution width(RDW)has been utilized as a prognostic indicator for mortality risk assessment in cardiovascular and cerebrovascular patients.Nevertheless,the prognostic significance of RDW in critically ill patients with cerebral infarction is yet to be investigated.The objective of this study is to examine the association between RDW and the risk of all-cause mortality in cerebral infarction patients admitted to the intensive care unit(ICU).Method:A retrospective cohort study was conducted using the Medical Information Mart for Intensive Care IV 2.2(MIMIC-IV)intensive care dataset for data analysis.The main results were the all-cause mortality rates at 3 and 12 months of follow-up.Cumulative curves were plotted using the Kaplan-Meier method,and Cox proportional hazards analysis was used to examine the relationship between RDW and mortality rates in critically ill cerebral infarction patients.Results:The findings indicate that RDW serves as a significant prognostic factor for mortality risk in critically ill stroke patients,specifically at the 3 and 12-month follow-up periods.The observed correlation between increasing RDW levels and higher mortality rates among cerebral infarction patients further supports the potential utility of RDW as a predictive indicator.Conclusion:RDW emerges as an independent predictor of mortality risk during the 3 and 12-month follow-up periods for critically ill patients with cerebral infarction.

Value of red blood cell distribution width in prediction of diastolic dysfunction in cirrhotic cardiomyopathy

BACKGROUND Clinical diagnosis of cirrhotic cardiomyopathy(CCM) often encounters challenges of lack of timeliness and disease severity, with the commonly positive indicator usually associated with advanced heart failure.AIM To explore suitable biomarkers for early CCM prediction.METHODS A total of 505 eligible patients were enrolled in this study and divided into four groups according to Child-Pugh classification: Group Ⅰ, Class A without CCM(105 cases);Group Ⅱ, Class A with CCM(175 cases);Group Ⅲ, Class B with CCM(139 cases);and Group Ⅳ, Class C with CCM(86 cases). Logistic regression and receiver operating characteristic(ROC) curve analyses were performed to determine whether red blood cell distribution width(RDW) was an independent risk factor for CCM risk. The relationships between RDW and Child-Pugh scores, Model for End-Stage Liver Disease(MELD) scores, and N-terminal pro-brain natriuretic peptide(NT-proBNP) were analyzed by Pearson correlation analysis.RESULTS A constant RDW increase was evident from Group Ⅰ to Group Ⅳ(12.54 ± 0.85, 13.29 ± 1.19, 14.30 ± 1.96, and 16.25 ± 2.13, respectively). Pearson correlation analysis showed that RDW was positively correlated with Child-Pugh scores(r = 0.642, P < 0.001), MELD scores(r = 0.592, P < 0.001), and NT-proBNP(r = 0.715, P < 0.001). Furthermore, between Group Ⅰ and Group Ⅱ, RDW was the only significant index(odds ratio: 2.175, 95% confidence interval [CI]: 1.549-3.054, P < 0.001), and it reached statistical significance when examined by ROC curve analysis(area under the curve: 0.686, 95%CI: 0.624-0.748, P < 0.001).CONCLUSION RDW can serve as an effective and accessible clinical indicator for the prediction of diastolic dysfunction in CCM, in which a numerical value of more than 13.05% may indicate an increasing CCM risk.

Prognostic value of red blood cell distribution width for severe acute pancreatitis

BACKGROUND Severe acute pancreatitis(SAP)is a common condition in the intensive care unit(ICU)and has a high mortality.Early evaluation of the severity and prognosis is very important for SAP therapy.Recently,red blood cell distribution(RDW)was associated with mortality of sepsis patients and could be used as a predictor of prognosis.Similarly,RDW may be associated with the prognosis of SAP patients and be used as a prognostic indicator for SAP patients.AIM To investigate the prognostic value of RDW for SAP patients.METHODS We retrospectively enrolled SAP patients admitted to the ICU of the First Affiliated Hospital of China Medical University from June 2015 to June 2017.According to the prognosis at 90 d,SAP patients were divided into a survival group and a non-survival group.RDW was extracted from a routine blood test.Demographic parameters and RDW were recorded and compared between the two groups.The receiver operator characteristic(ROC)curve was constructed and Cox regression analysis was performed to investigate the prognostic value of RDW for SAP patients.RESULTS In this retrospective cohort study,42 SAP patients were enrolled,of whom 22 survived(survival group)and 20 died(non-survival group).The baseline parameters were comparable between the two groups.The coefficient of variation of RDW(RDW-CV),standard deviation of RDW(RDW-SD),Acute Physiology and Chronic Health Evaluation II(APACHE II)score,and Sequential Organ Failure Assessment(SOFA)score were significantly higher in the non-survival group than in the survival group(P<0.05).The RDW-CV and RDW-SD were significantly correlated with the APACHE II score and SOFA score,respectively.The areas under the ROC curves(AUCs)of RDW-CV and RDW-SD were all greater than those of the APACHE II score and SOFA score,among which,the AUC of RDW-SD was the greatest.The results demonstrated that RDW had better prognostic value for predicting the mortality of SAP patients.When the RDW-SD was greater than 45.5,the sensitivity for predicting prognosis was 77.8%and the specificity was 70.8%.Both RDW-CV and RDW-SD could be used as independent risk factors to predict the mortality of SAP patients in multivariate logistic regression analysis and univariate Cox proportional hazards regression analysis,similar to the APACHE II and SOFA scores.CONCLUSION The RDW is greater in the non-surviving SAP patients than in the surviving patients.RDW is significantly correlated with the APACHE II and SOFA scores.RDW has better prognostic value for SAP patients than the APACHE II and SOFA scores and could easily be used by clinicians for the treatment of SAP patients.

Red blood cell distribution width in heart failure: A narrative review

The red blood cell distribution width(RDW) is a simple, rapid, inexpensive and straightforward hematological parameter, reflecting the degree of anisocytosis in vivo. The currently available scientific evidence suggests that RDW assessment not only predicts the risk of adverse outcomes(cardiovascular and all-cause mortality, hospitalization for acute decompensation or worsened left ventricular function) in patients with acute and chronic heart failure(HF), but is also a significant and independent predictor of developing HF in patients free of this condition. Regarding the biological interplay between impaired hematopoiesis and cardiac dysfunction, many of the different conditions associated with increased heterogeneity of erythrocyte volume(i.e., ageing, inflammation, oxidative stress, nutritional deficiencies and impaired renal function), may be concomitantly present in patients with HF, whilst anisocytosis may also directly contribute to the development and worsening of HF. In conclusion, the longitudinal assessment of RDW changes over time may be considered an efficient measure to help predicting the risk of both development and progression of HF.

Red blood cell distribution width: A marker of anisocytosis potentially associated with atrial fibrillation

The incorporation of biomarkers in the actually used risk scores seem to be helpful for early identifying atrial fibrillation(AF)patients at higher risk.The aim of this critical review of the scientific literature is to investigate the potential clinical significance of red blood cell distribution width(RDW)in AF.A systematic electronic search was carried out to identify all articles describing an epidemiological association between RDW and AF in adult human populations.Data abstraction was conducted on a final number of 35 articles(13 crosssectional,12 prospective and 10 retrospective studies).The results of these epidemiological investigations were all virtually concordant to emphasize that an enhanced RDW value is not only a predictive factor and a marker of AF but its measurement may also be helpful for predicting the risk of developing many adverse complications in patients with AF,such as recurrence and duration of AF,hospitalization for heart failure,bleeding,left atrial thrombosis and stasis,thromboembolic events and mortality.AF patients with RDW values exceeding the local reference range may be more aggressively investigated and managed,in order to identify and attenuate the impact of possible underlying disorders causing both anisocytosis and AF.

Red blood cell distribution width derivatives in alcohol-related liver cirrhosis and metabolic-associated fatty liver disease

BACKGROUND Looking for undiscovered blood markers of liver fibrosis and steatosis still remains an issue worth exploring.There are still plenty of unresolved issues related to the actual role of hematological indices as potential markers of liver function.AIM To study red blood cell distribution width(RDW),RDW-to-platelet ratio(RPR)and RDW-to-lymphocyte ratio(RLR) in alcohol-related liver cirrhosis(ALC) and metabolic-associated fatty liver disease(MAFLD).METHODS The study group was composed of 302 people:142 patients with ALC and 92 with MAFLD;68 persons were included as controls.RDW,RPR and RLR were measured in each person.Indirect and direct parameters of liver fibrosis were also assessed [aspartate transaminase to alkaline transaminase ratio,aspartate transaminase to platelet ratio index(APRI),fibrosis-4(FIB-4),gamma-glutamyl transpeptidase to platelet ratio(GPR),procollagen I carboxyterminal propeptide,procollagen Ⅲ aminoterminal propeptide,transforming growth factor-α,plateletderived growth factor AB,laminin].MELD score in ALC patients and nonalcoholic fatty liver disease(NAFLD) fibrosis score together with BARD score were obtained in the MAFLD group.The achieved results were compared to controls.Then a correlation between assessed markers was done.Diagnostic value of each investigated parameter and its suggested cut-off in the research group RESULTS RDW,RPR and RLR values turned out to be significantly higher in ALC and MAFLD groups compared to controls(ALC:P<0.0001;NAFLD:P<0.05,P<0.0001 and P<0.0001,respectively).RPR correlated positively with MELD score(P<0.01) and indirect indices of liver fibrosis(FIB-4 and GPR;P<0.0001) in ALC patients;negative correlations were found between PDGF-AB and both:RDW and RPR(P<0.01 and P<0.0001,respectively).RPR correlated positively with NAFLD fibrosis score and APRI(P<0.0001) in the MAFLD group;a positive relationship was observed between RDW and FIB-4,too(P<0.05).AUC values and suggested cut-offs for RDW,RPR and RLR in ALC patients were:0.912(>14.2%),0.965(>0.075) and 0.914(>8.684),respectively.AUC values and suggested cut-offs for RDW,RPR and RLR in MAFLD patients were:0.606(>12.8%),0.724(>0.047) and 0.691(>6.25),respectively.CONCLUSION RDW with its derivatives appear to be valuable diagnostic markers in patients with ALC.They can also be associated with a deterioration of liver function in this group.

Red blood cell distribution width in elderly hospitalized patients with cardiovascular disease

BACKGROUND Red blood cell distribution width(RDW)is elevated in patients with cardiovascular disease(CVD).AIM To determine RDW values and impact of CV and non-CV coexisting morbidities in elderly patients hospitalized with chronic CVD.METHODS This prospective study included 204 consecutive elderly patients(age 77.5[7.41]years,female 94[46%],left ventricular ejection fraction 53.00%[37.50,55.00])hospitalized with chronic CVD at the Cardiology Department of Larissa University General Hospital(Larissa,Greece)from January 2019 to April 2019.Elderly patients were selected due to the high prevalence of coexisting morbidities in this patient population.Hospitalized patients with acute CVD(acute coronary syndromes,new-onset heart failure[HF],and acute pericarditis/myocarditis),primary isolated valvular heart disease,sepsis,and those with a history of blood transfusions or cancer were excluded.The evaluation of the patients within 24 h from admission included clinical examination,laboratory blood tests,and echocardiography.RESULTS The most common cardiac morbidities were hypertension and coronary artery disease,with acutely decompensated chronic heart failure(ADCHF)and atrial fibrillation(AF)also frequently being present.The most common non-cardiac morbidities were anemia and chronic kidney disease followed by diabetes mellitus,chronic obstructive pulmonary disease,and sleep apnea.RDW was significantly elevated 15.48(2.15);121(59.3%)of patients had RDW>14.5%which represents the upper limit of normal in our institution.Factors associated with RDW in stepwise regression analysis were ADCHF(coefficient:1.406;95%confidence interval[CI]:0.830-1.981;P<0.001),AF(1.192;0.673 to 1.711;P<0.001),and anemia(0.806;0.256 to 1.355;P=0.004).ADCHF was the most significant factor associated with RDW.RDW was on average 1.41 higher for patients with than without ADCHF,1.19 higher for patients with than without AF,and 0.81 higher for patients with than without anemia.When patients were grouped based on the presence or absence of anemia,ADCHF and AF,heart rate was not increased in those with anemia but was significantly increased in those with ADCHF or AF.CONCLUSION RDW was elevated in elderly hospitalized patients with chronic CVD.Factors associated with RDW were anemia and CV factors associated with elevated heart rate(ADCHF,AF),suggesting sympathetic overactivity.

Relationship between red blood cell distribution width levels and atrial fibrillation in hypertensive patients

Background Information on the relationship between red blood cell distribution width(RDW)and atrial fibrillation(AF)in patients with essential hypertension are scarce.The study aimed to assess the relationship between AF and RDW in hypertensive patients.Methods We enrolled 432 hypertensive patients,including 350 AF patients and 82 patients as controls.Patients'demographic,clinical,laboratory and echocardiographic characteristics were recorded.The AF patients were further divided into the persistent and paroxysmal AF subgroups.Electrocardiograms were monitored to identify the cardiac rhythm during blood sampling,and based on the rhythm,the paroxysmal AF group was categorized into the presence(with AF rhythm during blood sampling)and absence(with sinus rhythm during blood sampling)groups.Results The AF group had elevated RDW levels than the controls(12.7%±0.8%vs.12.4%±0.7%,P=0.002),and the persistent AF subgroup had higher RDW levels than the paroxysmal AF subgroup(12.9%±0.8%vs.12.6%±0.8%,P=0.007).Furthermore,in the paroxysmal AF group,the presence group had higher RDW levels than the absence group(13.0%±0.6%vs.12.5%±0.9%,P=0.001).There was no significant difference in RDW levels between the persistent AF subgroup and presence group of the paroxysmal AF subgroup(P=0.533)and between the absence group of the paroxysmal AF subgroup and control group(P=0.262).In multivariate regression analysis,in hypertensive patients,the presence of AF rhythm is an independent predictor for increased RDW concentration(P=0.001).Conclusions The RDW may be associated with the presence of AF rhythm,which implies the importance of maintaining the sinus rhythm in hypertensive patients.

Prognostic significance of red blood cell distribution width in gastrointestinal disorders

The red blood cell distribution width(RDW) is a routinely measured and automatically reported blood parameter,which reflects the degree of anisocytosis. Recently,the baseline RDW was found to have clinical significance for assessing clinical outcome and severity of various pathological conditions including cardiovascular diseases,sepsis,cancers,leukemia,renal dysfunction and respiratory diseases. A myriad of factors,most of which ill-defined,have an impact on the red cell population dynamics(i.e.,production,maturation and turnover). A delay in the red blood cell clearance in pathological conditions represents one of the leading determinants of increased anisocytosis. Further study of RDW may reveal new insight into inflammation mechanisms. In this review,we specifically discuss the current literature about the association of RDW in various disease conditions involving the gastrointestinal and hepatobiliary systems. We also present some of the related measurements for their value in predicting clinical outcomes in such conditions. According to our data,RDW was found to be a valuable prognostic index in gastrointestinal disorders along with additional inflammatory biomarkers(i.e.,C reactive protein,erythrocyte sedimentation rate,and platelet count) and current disease severity indices used in clinical practice.

Association between red blood cell distribution width and the occurrence of cervical carcinoma

Objective:To explore correlation between red blood cell distribution width(RDW)and cervical carcinoma.Methods:50 cervical carcinoma patients and 75 healthy controls from the First Affiliated Hospital of Soochow University from June 2020 to December 2020 were involved as the patients group and the control group respectively.Demographic data were collected from routine blood tests and biochemistry examination,the correlation of RDW with hemoglobin(Hb)and c-reactive protein(CRP)was evaluated by Spearman rank correlation,and receiver operating characteristic(ROC)curve was drawn to analyze the diagnostic value of RDW for cervical carcinoma.Result:The levels of RDW,squamous cell carcinoma antigen(SCCA)and carcinoembryonic antigen(CEA)in patients with cervical carcinoma were higher than those in the controls.The levels of high-density lipoprotein(HDL),Albumin,Prealbumin,Hb,RBC and neuron-specific enolase(NSE)in patients were lower than those in the controls(all P<0.05).There was no statistical significance on the difference in other markers between the two groups(P>0.05).The AUC of RDW in the diagnosis of cervical carcinoma was 0.834.Based on Spearman's rank correlation coefficient analysis,RDW was positively correlated with Hb(r=0.434,P<0.05)and CRP(r=0.366,P<0.05)RDW,and was negatively correlated with hematocrit(r=-0.363,P<0.05),in cervical carcinoma group,cervical carcinoma subgroupⅠ-ⅡandⅢ-Ⅳwere higher than the control group(P<0.05).Conclusions:Elevated RDW is associated with the occurrence of cervical carcinoma,and it may have clinical value in the diagnosis of cervical carcinoma and the course of reaction.

UHAS-MIDA Software Package: Mass Isotopomer Distribution Analysis-Applying the Inverse Matrix for the Determination of Stable Isotopes of Chromium Distribution during Red Blood Cell Labelling

Clinical assessment of fluid volume status in children during malaria can be taxing and often inaccurate. During malaria, changes in fluid volume are rather multifarious and estimating this parameter, especially in sick children is very challenging for clinicians who frequently rely on indices such as long capillary refill times, tachycardia, central venous pressure and decreased urine volume as guides. Here, we present the UHAS-MIDA, an open-source software tool that calculates the red blood cell (RBC) concentration and blood volume during malaria in children determined using a stable isotope of chromium (53Cr as the label) by gas chromatography-mass spectrometry in selective ion monitoring (GC/MS-SIM) analysis. A key component involves the determination of the compositions of the most abundant naturally occurring isotopes of Cr (50Cr, 52Cr, 53Cr), and converting the proportions into a 3 × 3 matrix. To estimate unknown proportions of chromium isotopic mixtures from the measured abundances of three ions, an inverse matrix was calculated. The inverse together with several inputs is then used to calculate the corrected MS ion abundances. Thus, we constructed the software tool UHAS- MIDA using HTML, CSS/Bootstrap, JavaScript, and PHP scripting languages. The tool enables the user to efficiently determine RBC concentration and fluid volume. The source code, binary packages and associated materials for UHAS-MIDA are freely available at https://github.com/bentil078/Abaye-et-al_UHASmida
